Scam! They post fake job ads on craigslist then try to get you to go (by way of a subtly suggested link) and pay for this bull background check. It is simple psychology, like every scam. It is actually one of the more intelligent scams I've seen on the internet. Having said that is is pretty pathetic that someone with "their?" intellect would want to rip people off... Sad and stupid! Don't give them your hard earned money!
